Why is Chris Hadfield
influential?

Chris Hadfield is the astronaut who had the brilliant idea of bringing social media to space. During his stay at the International Space Station, he shared updates on life in space to Twitter and Facebook users, and filmed a cover of David Bowie’s “Space Oddity.” The result was, of course, viral. Hadfield, who retired after returning to Earth this year, expanded his reach into yet another field by releasing a new book, An Astronaut's Guide to Life on Earth last month. He'll be remembered not only for his astronomical accomplishments but for doing more than any other astronaut to make space accessible to the public. For a guy who has spent quite a bit of time in other dimensions, he’s certainly down to earth.
